I played my BB1200 at rehearsal last night, and I had a ruddy good time! Yes, there are fancier BBs, with active electronics, more pickups and sometimes even more frets, but the BB1200 is pure, distilled BB. You know you've got a good 'un when playing just seems effortless, the bass is doing what you ask without question or grumble and you can focus on other things (like giving the new singer the nods because they're getting up to speed with the cues).
The BB1200 is a cornerstone of bass history IMO - it deserves to stand alongside the P, J, Ray and T-bird in those type of conversations.
